GPA on the US 4.0 scale converts letter grades (A, A−, B+, etc.) to numerical points (4.0, 3.7, 3.3) weighted by credit hours. The calculator returns your weighted GPA along with total credits and quality points.
What is GPA?
The US 4.0 GPA is the standard for American universities. Each letter grade maps to a fixed point value: A and A+ = 4.0, A− = 3.7, B+ = 3.3, B = 3.0, B− = 2.7, C+ = 2.3, C = 2.0, etc., down to F = 0.0. Multiply each grade's points by the course's credit hours, sum across all courses, divide by total credits — that is your GPA.
Indian students applying to US universities (for MS, MBA, PhD) usually have to convert their CGPA or percentage to the 4.0 scale. There is no universal formula — different consultancies use different ones. WES (World Education Services) is a common third-party evaluator that produces standardised conversions accepted by most US universities.
GPA differs from CGPA in just one way: scale. A 4.0 is American; a 10.0 is Indian. The math is identical — weighted average of grade points, weighted by credit hours.
Computing GPA
- Letter Points
- Grade points—A=4.0, A−=3.7, B+=3.3, B=3.0, etc.
- Credits
- Course credits—credit hours assigned to each course

When you need a 4.0 GPA
US graduate school applications
Almost all US universities ask for GPA on the 4.0 scale. Some accept Indian percentages without conversion; most prefer the standard scale.
Internships at US companies
Some internship applications have minimum GPA cutoffs (e.g., 3.5). Check your number.
Scholarship applications
Merit-based US scholarships often require 3.5 or 3.7 minimum GPA.
Transcript evaluation
WES or similar services convert your Indian CGPA to a 4.0 equivalent. The calculator gives a self-estimate to compare.
Common mistakes to avoid
Treating A and A+ as different points
On the standard 4.0 scale, A and A+ are both 4.0. Some institutions use A+ = 4.3 (a 4.3 scale) — check your school's policy.
Forgetting to weight by credits
A 4-credit A is more impactful than a 3-credit A. The calculator weights automatically when credits are provided.
